Enemy? We'll kill them on the spot!

No one could have ever imagined this encounter between two generations so far apart.

On a clear day, Ariha Minori—a modern young woman—goes out shopping and meets an overly enthusiastic fan of the royal family, dressed in an eerily realistic cosplay. Strangely enough, she soon discovers that this "fan" is nothing of the sort—in fact, the young man is none other than Prince Senko von Minaguchi Hyōnko, a genuine lost prince from three centuries ago.



And so, after this fateful meeting, his unexpected stay in the modern era begins.



Will the prince ever find his way back?

How will Senko spend his time in the future?
